Geomagnetic field intensity in the first millennium BC from data on ceramics of the Los Villares archaeological monument (Spain)

The geomagnetic field variation pattern in the second and third quarters of the first millennium BC is obtained from data on ceramic material sampled in the Los Villares multilayer archaeological monument (Spain). The analysis of available data on the geomagnetic field variation in Spain over the last seven millennia shows that it is similar to the geomagnetic variation pattern observed in other Eurasian regions. The amplitude of the “fundamental” (8000-yr) oscillation (≈20 μT) estimated from the Spain data exceeds significantly its amplitudes in other regions, which supports the previously noted tendency to a westward increase in the amplitude of the fundamental oscillation.
